Assessment of Antibiotic Dispensing Practices and Antibiotic Resistance Trends in Community Pharmacies

Thesis Abstract

The inappropriate dispensing of antibiotics in community pharmacies remains a critical factor contributing to the rising prevalence of antibiotic resistance, which threatens global health systems through increased morbidity, mortality, and healthcare costs. This study aims to systematically assess current antibiotic dispensing practices in community pharmacy settings and analyze the corresponding trends in antibiotic resistance patterns among bacterial pathogens isolated from local clinical specimens. Specifically, the research investigates factors influencing dispensing behaviors, compliance with national antimicrobial stewardship guidelines, and regional variations in resistance profiles over a three-year period. Employing a mixed-methods approach, the study utilizes a cross-sectional design complemented by retrospective data analysis. The target population includes registered community pharmacists operating within metropolitan regions, stratified across both urban and peri-urban areas. A sample of 150 community pharmacists was selected through stratified random sampling to ensure representativeness. Structured questionnaires, developed based on the Theory of Planned Behavior, captured data on dispensing practices, knowledge, attitudes, and perceived barriers. Additionally, a survey of 300 patient case files was conducted to validate self-reported behaviors. Antibiotic resistance data were gathered from laboratory reports of bacterial isolates, with genotypic resistance markers identified through polymerase chain reaction (PCR) techniques. Data were analyzed using descriptive statistics, chi-square tests for associations, and multiple logistic regression models to identify predictors of inappropriate dispensing. Resistance trends over the specified period were examined via time-series analysis, with key findings interpreted within the framework of the Health Belief Model and the Theory of Diffusion of Innovations. Expected findings anticipate that a significant proportion of community pharmacists dispense antibiotics without appropriate prescriptions, often citing patient demand and time constraints as key influencing factors. It is hypothesized that such practices correlate with increased resistance rates, particularly among Escherichia coli and Staphylococcus aureus isolates, exhibiting multidrug resistance patterns that have escalated over the three-year span. The study also expects to identify gaps in knowledge among pharmacists regarding antimicrobial stewardship, alongside systemic barriers such as limited regulatory enforcement and inadequate continuing education. The research contributes novel empirical evidence on the linkage between community-based antibiotic dispensing behaviors and the regional epidemiology of resistance, filling a critical gap in the literature that often overlooks community pharmacists' roles outside hospital settings. It advances understanding of behavioral determinants influencing dispensing practices through the lens of behavioral theories, offering a nuanced perspective on intervention points for policy and educational reforms. The main conclusions emphasize that inappropriate dispensing practices significantly drive local resistance trends and that targeted interventions addressing identified behavioral and systemic factors are necessary for curbing resistance. The study recommends intensified training programs for community pharmacists, strengthening regulatory oversight, and implementing community education campaigns to improve demand management. Additionally, it advocates for establishing robust surveillance mechanisms to monitor dispensing behaviors and resistance patterns continuously. In sum, this research underscores the urgent need for integrated antimicrobial stewardship efforts within community pharmacy settings and provides evidence-based strategies for policymakers, healthcare professionals, and stakeholders committed to mitigating antibiotic resistance.
